Hi,

     I have some problems during the work .when I start the project, the error which mean 

         An Import-Package could not be resolved. Caused by missing constraint in bundle <com.fujitsu.storagesystem.evcp.EvcpService_3.0.0>

             constraint: <Import-Package: org.quartz; version="0.0.0">

        An Import-Package could not be resolved. Caused by missing constraint in bundle <org.quartz-scheduler.quartz_2.2.1>

             constraint: <Import-Package: com.mchange.v2.c3p0; version="0.0.0">

appeared.I looked up the FAQ, and i put the 3rd party library(org.quartz) i need in Export-Package,Import-Package and write its classpath in the Bundle-ClassPath,but it still didn't work.

    I tried to follow the QA "How to package a library as an OGSI bundle?",but when i create a temp.mf and click "run generation of MANIFEST.MF" ,the temp.mf has no change ,so this method i gave up. I also delete the

serves and create a new one to start ,it still here.

   I want someone to help me ,how to do with this problem ,thanks!
